I Application filed March 11, 1899.

To all whom it may concern: Be it known that we, ALFRED M. ACKLIN and WILLIAM J. PATTERSON, residents of Pit tshurg, in the county of Allegheny and State of Pennsylvania, have in vented a new and useful lmprovel'nent in Chain Conveyors; and we do hereby declare the following to be a full, clear, and exact description thereof.

Our invention relates, primarily, to chain and-sprocket gearing, and, secondarily, to

metal-casting apparatus or with other apparatus embodying conveyer mechanism,

\Vith these ends in view we have devisedthe means shown in the accompanying drawings, in which Figure 1 is a view,"partially in section and partially in side elevation, of a conveyer-,

chain and drive-wheels constructed in accordauce with our invention, a portion of the chain being broken away. Fig. 2 is a plan view of two of the wheels and a portion of the chain shown in Fig. 1, and Fig. 3 is a perspective view of one of the removable blocks.

. Referring now to the details of construc tion illustrated'in the drawings, the endless chain a is composed of open links of, the adjacent ends of which overlap suflicienL-ly to receive rods 1), the projecting ends of which may constitute axles for supporting wheels in cases where such devices are employed in connection with a track for guiding and supporting the chain and its load between its drive-wheels. As shown in the present case,

each link a partially supports two molds c, 1

the projecting flanges at the ends of the molds being bolted to the link, as indicated at c. It will be readily understood without further illustration or description that when the links are employed for the purpose just indicatedsemi No. 708,694." on model.)

two chains of like construction will be em: ployed'and located side by side a sufiicient distance apart so that both ends of the molds will besupp'orted in the manner indicated in 5'; the drawings. It will be further understood that buckets or receptacles of any suitable form and dimensions may be employed in lieu of molds, according to, the relations in which the mechanism is to be used.

In order to support and propel the chain a, we employ two sprocket-wheels d, the distauce between the shafts of which is obvi- I ously determined by the length of thechain and the amount of slack that it is desirable v or permissible for it to have. Each sprocketwheel 01 has a polygonal periphery, and each of its sides is provided with a lug e.' Theselugs are alternately arranged at opposite sides v of the-central plane of the wheel. in order-'70 that they may engage either the inner or the outer sides of the corresponding links of the chain, and thus prevent it from either slip ping off the wheel or getting out of aline'ment;

Intermediate the lugs e are triangular-shaped blocks f, preferably formed of chilled iron or some other hard metal. The blocks f are secured to the body of the wheel by means of bolts f, having heads fitting into T-slots in the blocks-and provided with nuts, openings 61' being provided in'the wheel to-permit of ready application and removal of said nuts. Each of the triangular blocksffis provided with a lug f in such position as to engage the rear end of a corresponding link'of the chain, the lugs being alternately/located,at' opposite sides of the central plane .Of the wheel, as well as properly spaced around-the periphery in order to secure this result.

While we have shown the lugs e and f as 0 arranged alternately at opposite sides of the central plane of the wheel (1, it is to be un:

derstoodthat such dividing-plane neednot be equidistant fromthe peripheral edges] In fact, thelugs may be alternately located on opposite sides of any plane that is pen pendicular to the wheel-axis, provided sum: cieut supporting-space is afforded at each'side',

It will be readily understood fromithe'illusri" tration and the foregoing descriptiontnatthe roo construction described possessesnp'u'suai mes, chanical strength, is not liableteittet outtof' tiall'y as described.

2; The combination with an endlesschain We claim asonr invmtion- 4 1. The combination with an endless chain order, a'nd is so designed that if any of the parts 'become broken or worn out in service they may be readily re placed.-. It willnalso be apparent that the Mmechanismis adapted for ns'e in many relations where it is desired to transmitpowe'r or to'convey'materials'from one point to" another.

' We .desire'fitto be understood, therefore, that our invention is not limited to the exact details of construction shown and described or'to use in the" relations specifically mentioned.

having overlapping links, of a drive-wheel therefor having removable peripheral blocks provided with. lugs which are alternately lo cated at opposite sides of a plane of the wheel that is perpendicular to its axis so as to engage the rear ends of the chain-links, substan having overlappinglinks, of a polygonal drive-wheel therefor. having peripheral blocks bolted thereto and provided with logs that are located at the angles of the wheel and alterhatel; at opposite sides of a plane that is perpendicular to the wheel-axis so as to engage the rear ends of the chaindinks, sub-i stantiallyas described.

3. The-combination with an endless chain having overlapping links, of a drive-wheel having removable blocks provided with lugs and having guide-ribs intermediate said lugs,

said guide-ribsand said lugs being both located alternately at'opposite sides of a' plane of the wheelthat is perpendicular to its axis, 7
